ABSTRACT

Modification of the conventional ultrafiltration/microfiltration membranes is required to achieve selective separation of heavy meal ions from aqueous solutions. Studying of compaction factor of the prepared membranes is important to distinguish the morphological structures of the membranes, particularly the membrane sublayer configuration. Water contact angle measurement is an effective technique for investigating the hydrophilicity nature of the prepared membranes. Cellulose acetate (CA) among the hydrophilic polymers is considered as the most important organic ester of cellulose due to its abundance and broad applicability for the synthesis of different products because of tough, biocompatible, hydrophilicity characteristics, and it is moderately less expensive. Polysaccharides characterized by cellulose and its derivatives have fascinated researchers as environmental friendly materials. The grafting copolymer of the CA with the second polymer containing functional groups, such as poly methyl methacrylate, could radically increase the interaction of CA polymer with a wide range of materials.
